To all 'whom t may concern:

Be it known that I, HoMER C. BosTIAN, a citizen of the United States ofAmerica, residing at East Rochester, in the county of Monroe and Stateof New York, have in` vented certain new andv useful Improvements inRail-Drilling Apparatus, of which the following is a specification.

The object of this invention is to provide a machine for drilling theholes into the web of the rails of a railroad track in which holes thetie rods of the track are anchored.

Another object of this invention is to so construct this machine thatcan lbe fastened to and adjusted on the rail on the outside of the trackafter the track is laid so that the drilling operation can take placewhile cars run over the track.

With this machine v holes can therefore be drilled into the rails`during the repair of a track or they laying of a new track without theinterruption ofthe car service over the track during; the drillingoperation,

In the accompanying drawings:

Figure` l is a front eleva-tion of the drill ing machine.

Figure 2 is a top plan view of the machine.

Figure 3 is a side elevation chine. j

In the several figures of the drawings like reference numerals indicatelike parts.

The present practice for drilling the holes into the web of rails ofrailroad tracks after the track has been laid is to anchor a drillingapparatus between the two rails of the track or on top of the track andproceed to drill the holes untilfthe drilling interrupted by a car thatis ready to run over the track at1 the point ,where the drillingoperation takes place. The drill must then be removed to let the carpass. The car service is thus held` up while the'drilling operationtakes of the maplace and when the drilling apparatus is Y reinoved tolet the ca r pass the drilling operation is interrupted. In this way thelaying of the trackI as wellvas the car service over the track is'delayed b the drilling of the .holes into Qtheweb of t erails.

This delay is eliminated with the use of the ydrilling machine formingthe subject matterl of my present invention, as this machine is built ina manner that permits it to be clamped to the rail to bedrilled on theoutside of the track. The operator of the drilling machine can,therefore, use the drilling machine and drill holes while cars run overthe track that is being drilled.

This machine, as illustrated in the figures of the drawings. is built upof the bed plate l having the supporting arm '2 projecting outon oneside thereof. This supporting arm is located intermediate of the bedplate and forms an integralpart thereof. On the under side it isreinforced by the ribs or flanges 3 and a. whichv also form an invertedchannel Vvon the under side of the armin which the movable clampingmember 5 is mounted to slide.

On the outer end `of the, arm at the top thereof is formed the jaw 6which is adapted. to engage one edge ofthe 'base of the rail on whichthe machine is to be supported. A paircf jaws 7, 7 are formed on the endof the movable clamping member 5. f These are located opposite to the 6on ,top of the supporting arm` 2. For thispurpose the arm 2 is providedwith the openings 8. S through which the jaws 7, 7 of the movable member5 project to slide back and forth therein. Y s

Fastened yto the under side of the arm Q between the ribs 3. and A ismounted the bearing block 9 and in line with this bearing block on the.under side of the bed plate l is provided a second bearing block 10.These two bearing blocks support the Vclamping screw between them andallow it to be turned by means of a wrench at the front or back of themachine. For this purpose the outer ends of the .screw 11 have a squarehead formed thereon that can be readily -taken hold of bv the wrench.

be moved toward or away from the 6 on the rotation of the screw 11. Inthis way the parallel edges of a rail can be rigidly clamped betweenthem to support the arm 2 and in turn support the bed plate 1 on theunder` side of the rail. i

The bed plate 1 has the under cut rail 13 formed integral along one sidethereof and the adjustable` rail 14 suitably clamped to the Vbase on theopposite side thereof. A c dovetailed channel is thus formed on top ofthe bed plate in which the base plate 1li of the carriage carrying thedrilling mechanism is adjustably clamped in place. At the left hand endof `this base 15 is hinged a second` base plate 16. This second rbaseplate overlapsv the kfirst base plate and is mounted to swing on the pin17 supported in the lugs18 and 19 of the first baseV plate. The otherend of the swinging base plate has an adjusting screw 2O threadedtherein. This adjusting screw passes through the swinging` base plate 16and its end rests on top of the base plate 15. On the rotation of thescrew by means of the handle 21 formed on said screw the swingingv baseplate 16 is slowly raised at that end while the other end swings on thehinge pin 1T as illustrated in Figure 1. This is for a pur pose thatwill presently7 appear.

Mounted on the top of the second base plate is the drilling mechanismproper. This mechanism comprises the bearing blocks 22 and 23. Thesebearing blocks are in line with-each other and are suitably anchored tothe swinging base plate 16. In the bea-ring block 23 is mounted torotate the end of the drill spindle 24 and in the bearing block 22 ismounted to slide the sleeve 25 in which in turn is mounted to rotate thespindle 24. The sleeve 25 has a rack 26 cut-A into one side thereof withwhich the pinion 2T is adapted to'mesh. The pinion 27 is mounted on thevertical shaft 28 within the bearing block 2 2 and adjacent to the rack26 formed on the feed sleeve 25. To the upper end of the vertical shaft`=26 isl keyed the worm gear 29 which is adapted to mesh with the feedworin 30. This worm is carried onthe horizontal shaft 31 which ismounted to rotate between the bearings 32 and 33 supported above thebearing block 22. On onefend of the shaft ,31 is mounted the feed wheel34 kand on the other end of this shaft is mounted the ratchet wheel 3,5and ratchet handle 36.V In this way the shaft 31 may be rotated xbyeither the feed wheel 34 from one side of the machine or with theratchet handle :36 from theot-her side of the inachne, In rota-ting theshaft 31 and its Worm BO-the sleeve 25 slowly feeds the drill spindle24,t-oward or vaway from the web ofthe rail, to which the machine isclamped.

c The drill spindle 24 carries,r on the outer end a chuck which `the`*drill 38 is held in place. Keyed to the drill spindle 24 ahead of thebearing bloeit 23 is the worm gear 39. This worm gear meshes with theworm 40 carried on the armature shaft. 41 of the inotor 42. Yfhe motor42 is mounted on top of the swinging base plate 16 on one side of thedrilling mechanism heretofore described and is adapted to rotate thespindle shaft 24 by means of the worin 40 and worm gear 39. The woringear is splined on the spindle shaft 24. This permits the shaft to slidethrough the gear in order to feed the drill 3S toward or away from theweb of the rail. rlhe free end of the armature shaft is supported by thethrust bearing 43 15 is mounted in the bed plate 1, being. clamped inplace in the dove tailed channel formed at the top thereof. For thepurpose of adjusting the base plate on the bed plate the rail 14 on oneside of the bed plate 1 is loosened to allow the4 base plate 15 to movelaterally thereon. This is done by prying the base plate along the bedplate by means of a bar and is facilitated by the central row of teeth45 formed in the bed plate between which the end of the bar can besuccessively inserted as the base plate 15 isv moved forward on the bedplate 15. lllhen the desired position has been reached the base plate 15is again fastened to the hed plate by clamping it in place thereon bymeans of the rail 14. After the horizontal adjustment of the drillingmechanism has been made in this way it can be raised by raising one endof the swinging base plate 16 on the base plate 15. This is done byrotating the screw 20 so that the base plate 16 is lifted by it. Thedrill spindle 24 is thus raised tothe properfheight to bring it in linewith the point in the rail where the hole is to be drilled. To guide theswinging base plate 16 while it is being raised or lowered on the baseplate 15 a vertical post .46 is anchored on the base plate 15. This postprojects through the slot 47 in the base plate 16 and keeps the two baseplates in perfect alignment with each other.

The operation of the `drilling machine is as follows:

The bed plate 1 is moved against the side of lthe rail to be drilled andis allowed to rest lon the ends of the ties to which the rail is spiked.In this position the support-k ing arm extends under the rail betweentwo of the ties and itsjaw engages the inner edge of the base of therail.V The screw 1-1 is then rotated from either one side o r ,the otherside of the machine until the jaws 7, 7 formed kon the outer end of themovable clamping member 5 engage the outer edge of the base of the rail.The base of the rail is thus tightly clamped between the jaws ics 6 and7 sothat the arm vsupports the drilling machine firmly onthe rail. Thelateral adjust-ment of the drilling machine is then made by moving thebase plate 15 along the bed plate l as above pointed out. Then this isdone the drilling mechanism is adjusted vertically by means of the screw20 until the drill carriednon the end of the spindle is in line with thepoint where the hole is to be drilled in 4 the web of the rail. Themotor is then started and the drill fed toward and into the rail bymeans of the spindle 24. hand wheel. provided on one side, or theratchet handle provided on the other side of the machine mayT be used toregulate the feed as above pointed out.
